Title: XJ swapping the engine this weekend
Post by: 5speedcobra on August 02, 2014, 02:53:43 PM

Hi All,

I'm going to swap the 4.0 that holds no oil pressure once it warms up with one with 130,000kms on it. I've done more than enough engine swaps in other cars, but those were all FWD.  From the looks of it, taking the 4.0 out should be pretty straight forward. Just wondering if you guys have any tips for me to make the swap go smooth?

I'm thinking the hood, front clip, and rad should all come out. As for the AC compressor and AV rad, I was wondering if it's advisable to just move them off to the side?
I was also wondering if it's easier to leave the intake and exhaust manifolds in or, if I should remove them before pulling the engine.

It is a 5 speed, so I'm gonna change the clutch while I'm there anyway.

Thanks ahead of time!

Cristian

Remove re hood, rad and fan. That will be plenty of room

I find its easier to remove the intake and exhaust manifolds from the engine before removal.
And installation of said manifolds on replacement engine before it goes back in.
Removing hood, front clip, and rad for sure. The A/C stuff can be set to the side, don't have to disconnect any of it.

Every time I've done it, I've brought out the engine/tranny/tcase all together as a single unit. Easier to disconnect each piece once its out.
This does require a tall ceiling in your garage, with nothing obstructing the way. If you have low rafters in the way, this may not be possible.

Last time I did an XJ the hood stayed on, undo the limiting straps and it opens up farther. The front clip and AC stuff all stayed in, just laid it off to the side. Take off fan and removed rad. Lots of room then. Support the tranny. Manifolds stay on.

Change the pilot bearing in the crank. Princess auto sells a decent puller.

I'd also remove the exhaust and intake.  Take a very close look at both sides of the exhaust, check for cracks and signs of leakage. Your odds are good that at least one of the 2 won't have a crack (maybe wishful thinking).
